Actually it is not that difficult .. In a nutshell you download that small programme (Win32 Development Tools ) and run the relevant cpu programme
Then type the command xbootmgr -trace boot -prepSystem -verboseReadyBoot into an elevated prompt
The system will reboot 6 times and all you need to do is allow the tool to elevate (UAC) after each boot
My 7 boot time is sub 30 seconds
